      The QML formatter in QtCreator failed to format the following qml content:

      import QtQuick

Item {
    onDataChanged: (data) => { // Notice the "(data) =>" arrow function expression
        if (someCondition)
            console.log("function called")
        doSomethingElse()
    }
}

       

      However, the signal handler written in the following format passes the formatter.

      import QtQuick

Item {
    onDataChanged: function (data) {
        if (someCondition)
            console.log("condition matched")
        doSomethingElseWithData(data)
    }
}
